, LOGGING HOOK.

Application filed August 20, 1927. Serial No. 214,250.

My invention relates tologging hooks which are tubular in shape, have a swivel at one end, and ridges projecting from the inner wall of the tube.

The objects of my invention are to provide a hook which has no'sharp, protruding corners and is therefore least liable to catch in any obstacles; which permits the hook to rotate freely at all times and thereby to prevent the cutting of the choker; which has provisions for the facile insertion of the choker; and which contains safeguards against the accidental unhooking of the choker.

Other objects and advantages are to be found in the construction and arrangement of parts as will be described in the specification and particularly pointed out in the appended claims.

I attain these objects with the mechanism illustrated in the accompanying drawings, in which:

Fig. 1 is a front elevation of my hook.

Fig. 2 is a section through Fig. 1 along the line 22.

Fig. 3 is a section through Fig. 2 along the line 33.

Similar numerals refer to similar parts throughout the several views.

The hook consists of a tubular housing 1 having both ends closed and all exteriorly protruding corners rounded off. The stem of a swivel 2 is inserted in the top and held by a washer 3 at the inside of the housing.

A round hole 4 in the side wall of the housing serves for the insertion of the ferrule 5. A slot 6 extending from the front'or round hole 4 to the bottom of the housing permits the choker 7 which is securely fastened to the ferrule to assume a position in alinement with the axis of the housing when the ferrule comes to a seat in the bottom of the housing. An oblong hole 8 in the rear wall of the housing provides the necessary clearance for the turning of the ferrule 5 while being taken in or out. In the interior of the housing there are three ridges 9, 10, and 11 extending across the housing and past the edges of the holes 4 and 8. The two upper ridges 9 and 10 serve merely for the guidance of the ferrule 5, and the distance which they approach each other is immaterial, provided they leave sufficient space for the insertion of the washer 3 and the riveting of the swivel 2. It should, however, be observed that the plane of the two ridges 9 and 10 does not cut the axis of the housing at right angles, but rathcrproceeds obliquely upward from the edge of the front hole l toward the edge of the rear hole 8. The purpose of this construction is to make it easier for the workman to insert the ferrule 5, in so far as an upward direction of insertion requires less lifting and bending of the heavy choker; less bending also prolongs the life of the choker. The third ridge 11 at thebot'tom edge of the front hole 4 proceeds parallel to the ridge at the upper edge, but besides the function of guiding the ferrule during insertion, has the additional duty of preventing the ferrule which is subject to continual jumps and jerks, from jumping straight toward and through the front hole 4. To accomplish this purpose more effectively I prefer to extend this ridge 11 as far as practicable toward the interior of the housing, so that the edge will overlap to a certain extent the nearcst edge of the ferrule 5. It is of course necessary that the slot 6 in the housing be extended through'the ridge 11.

will be seen that my objects have been accomplished and, though I have shown the preferred form of construction, I reserve to myself the right to make minor changes providing I do not contravene the spirit and principle of my invention.

I claim: 7 v

1. A logging hook, comprising a tubular housing closed at the top and bottom, a swivel attached to the top of the housing, the bottom of the housing being adapted to hold the ferrule of the choker, a round hole in the side wall of the housing, an oblong hole in the side wall of the housing opposite the round hole, the upper edge of the oblong hole being higher than the upper edge of the round hole, a ridge in the interior of the housing at the bottom of the round hole, and a slot in the housing, said slot extending from the bottom of the round hole, through the ridge to the bottom of the housing.

2. A logging hook, comprising a tubular housing closed at the top and bottom and having all exteriorly projecting corners rounded off, aswivel rivetted into the top of the housing, the bottom of the housing being adapted to hold'the' ferrule of a choker, a round hole in the side wall of the hous- Having thus described my invention it ing, an oblong hole in the side wall of the housing opposite the round hole, the upper edge of the oblong hole being higher than the upper edge of the round hole, and ridges at the upper edges of both holes said ridges 7 extending toward the interior of the housing swivel attached to the top of the housing, the bottom of the housing being adapted to receive the ferrule of a choker, u round hole in the side wall of the housing, an oblong hole in the side wall of the housing opposite the round hole. a ridge at the upper edge of the oblong hole and extending to ward the interior of the housing, a ridge at the bottom edge of the round hole and extending toward the interior of the housing, the edge of said last-named ridge overlap ping the nearest edge of the ferrule, and a slot in the housing, said slot'extending from the bottom of the round hole through the ridge and to the bottom of. the housing.

In testimony whereof I aiiix my signature. CHARLES WILLIAM SFIERING.
